WILLIAM SWINDELL, OF ALLEGHENY, PENNSYLVANIA. I

GAS-PRODUCER.

SPECIFICATION forming part of Letters Patent No. 689,660, dated December24, 1901.

Application filed August 9,1901. Serial No. 71,466. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM SWINDELL, of Allegheny, in the county ofAllegheny and State of Pennsylvania, have invented a certain new anduseful Improvement in Gas-Producers, of which improvement the followingis a specification.

My presentinvention relates to gas-producers of the general class ortype which is set forth in Letters Patent of the UnitedStatesv No.674,101,'grantedand issued to me under In the accompanyingdrawings,Figu-re 1 is a 3 vertical longitudinal central section throughT a gas-producer, illustrating anapplication of my invention; Fig. 2,;ahorizontal section through the same on the line b b of Fig. 3;

Fig. 3, a transverse section on the liner a of;

Fig. 2; Fig. 1, a horizontal section on the line 0 c of Fig. 5, showinga modification of structural detail; and Fig. 5, a transverse section onthe line (Z d of Fig. 4.

In the practice of my invention the vertical Walls of the producer are,as heretofore, built of suitable masonry, preferably of substantiallyrectangular contour, as shown in Figs. 2 and 4, and, as in Patent No.674,104 aforesaid, inc'lose a central chamber, the upper portion ofwhich is in this instance divided into two compartments and which iscovered and closed at its top by an arched roof 3 and may be, as in saidpatent, termed the gasdischarge chamber and also inclose two or morelateral generating-chambers 11. Four generating-chambers,two of whichare located on each side of the central gas discharge chamber, areherein shown; but a greater or less number may be employed, in thediscretion of the constructor,withou t departure from the spirit of myinvention. I

The side walls of the producer are inwardly sloped or inclined from thelower ends of the generating-chambers (which, similarly to thegas-discharge chamber, are open at their bottoms) to the tops ofcorrespondingly-inclined grates 4, which are supported below them-on theproducer-walls. Longitudinal blast-pipes 5, towhich currents of steamare supplied by pipes 6, controlled by a valve or valves 7, ex-

tend along the lower sides of the grates 4:.

ed to be water-sealed, transverse plates 9 extending across the ash-pitto a level below that at which water may normally stand therein, asshown in Fig. 1.

A transverse partition-wall 10 is built in the central gas-dischargechamber, said wall extending from the inner wall of thegenerating-chambers 11 on one side thereof to that of thegenerating-chambers on the opposite side and from the roof 3 to or nearthe bottoms of said inner walls, said partitionwall di'viding the upperportion of the gasdischarge chamber into a receiving-compartment2, whichcommunicates witheach of the generating-chambers, and adeliverycompartment 2, from which a dischargerpassage 15 leads to adesired point of gas-delivery.

As shown in Figs. 1 to 3, inclusive, each of the generating-chambers 11communicates directly and independently with the receiving-compartment 2through a port 11 in the inner wall of the generating-chamber.

In the modification shown in Figs.,4= and 5 two of thegenerating-chambers communicate directly with the receiving-compartment2 through ports 11*, as above described, While the other twogenerating-chambers communicate indirectly with said compartment throughthe two generating-chambers first specified, ports 11 being provided forthis purpose in the partition-walls which separate the adjoininggenerating-chambers.

The discharge-passage 15, which leads out of the upper portion of thedelivery-compartment 2 of the gas-discharge chamber, is controlled by adamper 18 and extends down wardly to a point of connection with awatertrough 16, from the opposite'end of which a delivery-pipe 17 is ledto the desired point of delivery of the gas. The water-trough ispreferably providedwith suitable appliances for the separation of tar,soot, and other prodnets which pass with the gas from thedelivery-compartment, said appliances not, however, constituting part ofmy present invention and not being, therefore, herein at length setforth.

In the operation of the producer fuel is charged into and maintained incombustion in the generating-chambers 11, the solid residuum passingdown and being supported on the grates 4. The gas generated by thecombustion of the fuel in each of the generatingchambers passestherefrom into the upper portion of the receiving-compartment 2 of thegasdischarge chamber, either directly through a port 11 orintermediately through a port 11, into an adjoining generating-chamber,and thence through the port 11 of the latter chamber into thereceiving-compartment. From the receiving-compartment 2 the gas passesdownwardly under the bottom of the partition-wall into thedelivery-compartment 2, and thence through the discharge-passage 15 andwater-trough 16 to the delivery-pipe 17. The several generating-chambers11 are successively charged with fuel at such intervals that there maybe a comparatively bright fire in one or more of them at the time whenanother is charged. The gas which is first evolved from the fresh chargemeets and mingles in the receiving-chamber 2 with the purer and hottergas from the generating-chambers in which the charges of fuel have beenmore highly heated and more completely converted into gas, and thesmoke, soot,and other foreign matters of the gas of the fresh charge areconsumed in such admixture.

' wall 10 prevents the gas of the fresh charge The partition-- fullutilization of the gaseous elements of each of said charges.

I claim as my invention and desire to secure by Letters Patent 1. In agas-producer, the combination of a gas-discharge chamber,generating-chambers located on opposite sides thereof and havingseparate fuel-supply openings, a fuel-support below and open to each ofsaid chambers, ports establishing continuous communication between thegenerating-chambers and gasdischarge chamber, a discharge-passageleading out of the gas-discharge chamber, and a partition-wall extendingacross the upper portion of the generating-chambers and the gasdisehargechamber.

2. In a gas-producer, the combination of a gas-discharge chamber, aplurality of generat ing-chambers located on opposite sides thereof andhaving separate fuel-supply openings, ports establishing continuouscommunication between one of the generating-chambers on each side of thegas-discharge chamber and said chamber, ports establishing continuouscommunication between the several generating-chambers on each side ofthe gas discharge chamber, and a discharge-passage leading out of thegas-discharge chamber.

3. In a gas-producer, the combination of a gas-discharge chamber,divided transversely into receiving and delivery compartments,generating-chambers located on opposite sides thereof and havingseparate fuel-supply open= ings, a fuel-support below and open to thegenerating-chambers and the compartments of the gas-discharge chamber,ports establishing continuous communication between thegenerating-chambers and the receiving=compartment of the gas-dischargechamber, and a gasdischarge passage leading outof thedeliverycompartment of said chamber. v
